Time Restricted Feeding in Autosomal Dominant Polycystic Kidney Disease

Is this Study for You?

Let's Get Started!


We want to study how feasible it is to restrict eating to 8 hours a day. Both groups will participate in a group-based, behavioral dietary intervention for 1 year (initially weekly, then monthly meetings). We will also look at changes in markers in the blood and both the size of the kidneys and amount of fat tissue in the abdomen by MRI. The results of this study will help design a larger study where we can test if restricting hours of eating can slow progression of ADPKD.
